don't understand your question, but will try to explain what _may_ have
been
your question.


I don't understand you explanation.....


An a/c unit will use about 1,400 watts electricity input to remove every
1,000
watts of heat.

The Mermaid Marine a/c in question here is rated at 6500 BTU, and draws 6.4
amps at 120 volts. That is 768 watts of input power.

The a/c is rated at "6500 BTU", which is really 6500 BTU per hour
(manufactuers tend to leave off the "per hour" part of the specification).
This unit has an EER (energy efficiency ratio) of 6500/768= 8.5, which is
comparable to a typical window mounted A/C.
